A Lateral View Of The Inferior Costal Facet Of The Thoracic Vertebra

Description

Rotating in a lateral perspective, the animation isolates the inferior costal facet (fovea costalis inferior) on the thoracic vertebral body, a crescentic articular surface positioned on the posterolateral margin of the inferior vertebral body. As the vertebra turns, the relationship of the facet to the pedicle, vertebral foramen, and the inferior vertebral notch becomes clearer, with the transverse process and superior articular process providing posterior context. The sequence keeps the viewer oriented to superior versus inferior endplates while the facet remains the focal landmark. Clinically, this small facet matters because it forms part of the costovertebral joint where the head of a rib articulates with adjacent vertebral bodies, and it helps explain why thoracic pain can be referred and mechanically linked to respiration and trunk rotation. Costovertebral and costotransverse arthropathy, inflammatory spondyloarthropathies, and rib head subluxation after trauma are easier to conceptualize when you can track the articular surface in space rather than infer it from a single still. Orientation is the point. The moving lateral view also reinforces a frequent teaching pitfall: the inferior costal facet sits on the vertebral body, not on the transverse process, and it aligns with the rib head rather than the rib tubercle. Use this animation in thoracic spine anatomy labs, radiology teaching files when correlating oblique CT or parasagittal MRI through the costovertebral region, and in orthopedic or pain medicine content discussing thoracic segmental dysfunction and rib head injections.
